Abstract: The invention relates to a method of controlling a subsea platform. The method comprises a step of providing a database containing object information of objects identified in an environment wherein the platform is operating, and a step of generating visualization data of said objects. Further, the method comprises a step of receiving camera image data from a camera unit disposed on the subsea platform, and a step of composing an image structure based on the object visualization data and the camera image data. Here, the visualization data of said objects are generated using synthetic models thereof.

Abstract: A method is presented for simulating marine assets (MA) in an offshore operation. The marine assets comprise at least an anchor, a line coupling the anchor with a winch, and a support platform located offshore for supporting the winch. The method involves a computation stage for estimating a state of the marine assets using a computational model and received sensor data (Ds) pertaining to a state of the marine assets and/or of an environment (ME) wherein the marine assets are used. The computational model of the marine assets (MA) includes at least a specification of an anchor, a specification of a winch and a specification of a line coupling the anchor with the winch. The at least a line is modeled as a first portion extending between the winch and a touch-down point where the line touches the seabed and a second portion extending between the touch-down point and the anchor.
